A. If the CONFIG PARK BRK ON warning does not come into view when the PARK BRK control switch is at ON (during flight phases 3 and 4):
- set the PARK BRK selector switch to ON.
- do a check for a ground signal at pin B/E of the parking brake electrical control valve (72GG) (Ref. ASM 32-45/01).
(1) If there is no ground signal:
- do a check for a ground signal at pin B/D of the parking brake electrical control valve (72GG) (Ref. ASM 32-45/01).
(a) If there is no ground signal:
- do a check and repair the wiring from the pin B/D of the parking brake electrical control valve (72GG) to the ground terminal (Ref. ASM 32-45/01).
(b) If there is a ground signal:
- replace the CTL VALVE-PARK BRK,ELEC. (72GG) (Ref. AMM TASK 32-45-51-000-001) (Ref. AMM TASK 32-45-51-400-001).
